I need Two at least 5" O-Rings for my OmniFilter but any 5" O-ring may work. I have met with a Jersey Wall of superior strength. Help, John

Hi John: The Omnifilter OK25 O-ring is about 4 1/8" O.D. and would not fit in place of a 5" O-ring. Thank You, WaterFiltersOnline

I really don't know, but perhaps the Culligan site could help you. We have an Omni whole house water filter and use it to filter out sand and sediment. This is the same type filter we had been purchasing from Walmart and the home improvement stores. After going through a period where these filters were out of stock and just weren't available at any of those stores, we were glad to find them at Amazon and for a better price. We just re-ordered them again from Amazon.

Mr. Fenels, the dash size, each dash is the size of o-ring set of the old o-ring to dash size or the width of o-ring grove which the o-ring fits into. I don't know why they just don't say this size (in inches) fits this size ring ?? The set I got is in "Inches". I try to get the old o-ring off and size it with the new one then just slip the new one on. I have used several of these O-rings since got the kit, plus have used some as stops/holders on rods I like to keep in place, they can be used for many other little jobs besides what they were intended for. They seem to be high quality rings. Hope this will help you. Best regards, Charles

I'm not sure about the o-ring. My system did not come with a filter, so it was fortunate that I had ordered a spare filter. A plumber installed it for me, but I assume whatever was needed came with the system... other than the filter, of course!

Amazon sells replacement O-ring on their site... Check the diameter measurement and see if they have it in that size. Search for silicon O-ring.

If you have a heavy equipment/hydraulic cylinder repair shop near you they should be able to match the O-ring. As soon as you get the stuffer take the O ringin and have them match it ahead of time, that way if you have a blow out you can fix it in two minutes

You will need to have the model number of your undersink filter. Search for replacement O-rings for that model. Its the only way you'll know if you're getting the correct o-ring.

I think you have to provide your own threaded barb fitting. Y ouc ould choose the outlet diameter at that time. Get high temp silicone hose. I can tell you that the o ring seals are crap. I took mine up to the homebrew shop and bought replacements. Once you can get it to stop leaking, it makes a good hot liquor tank.

They don't sell the o-ring by itself; you'll have to order a replacement reservoir ($14 for the 70-oz). http://store.petfountain.com/filters-accessories

There are a couple of different sizes used. This turned out to be too large for my filter. I would recommend finding out what size bolt you have first. Either use a gauge or try a nut of known size.

Mike: silly question, but did you give the filter an extra push, plus push in the top rubber gasket some more to expose the thread? If this fails then the filter is too long. In that case I would be making an extended threaded mounting post. Or a special nut with a reduced diameter that will go inside the filter and catch the thread. My 10 gallon Craftsman has a 7/16 NC thread. I have the capability at home to manufacture these fixes, but if you do not I am at a loss for other solutions. Hoe about a recessed cup with a flange, then cut a bigger hole in the filter rubber and use a 7/16 nut inside the cup.

Unfortunately the connectors on these pads are for 3mm snap on connections. Omron uses smaller connections, so these pads will not fit correctly.

My o-ring leaked at first, and my dad jut kept taking it off and putting it back on and tightened it until it quit leaking. I thing what happened is that it wasn't going o the threads correctly. I hope this help you!!! Be blessed!!!

You really don't need a certain size filter. I use regular size filters by folding them to fit. Works for me!

If you can't get one from the manufacturer, try using a rubber O ring which you can buy from your local hardware store.

not sure if you will find one that size; i have the 17x20" filter. Works well, but scratches easy and must be mounted on a support frame.
